+Provide an OpenAI API transcribe server.
+
+
+## Build Docker Image
+
+```bash
+docker-compose build
+```
+
+or
+
+```bash
+docker build -t sensevoice-openai-server .
+```
+
+## Start Server
+
+### Docker Compose
+Change volumes in docker-compose.yml to the path of the model you want to use.
+
+```bash
+docker-compose up -d
+```
+
+### Docker
+```bash
+docker run -d -p 8000:8000 -v "/your/cache/dir:/root/.cache" sensevoice-openai-server
+```
+
+## Usage
+
+```bash
+curl http://127.0.0.1:8000/v1/audio/transcriptions \
+ -H "Content-Type: multipart/form-data" \
+ -F model="iic/SenseVoiceSmall" \
+ -F file="@/path/to/file/openai.mp3"
+```
